Can you use sandpaper on your teeth?

No. Using sandpaper on your teeth is extremely dangerous. The abrasive material in sandpaper can damage the enamel of your teeth, causing long-term damage and sensitivity. The surface of sandpaper is so rough that it could also cause cuts or abrasions to the gums and oral tissues. In addition, the particles of sandpaper can become embedded in the teeth and gums, leading to further irritation.

Please remember that sandpaper should only be used on inanimate objects, and should never come into contact with your mouth or any part of your body. If you are concerned about the appearance or health of your teeth, it's best to consult a dentist or dental professional for advice and appropriate treatments.
